Running Out Soon? “Power Generation Warning” Oil-Cooled 1100/1200 Generator Issues

24 September 2023

SUZUKI Part Number
[ 31400-03F40 ]＝31400-03F41 Consolidated
Generator ASSY

This part number is
Bandit 1200K6 and GS1200SS
Supposedly the final model

The generated voltage is also kept modest at 14V range
Safe to use with lithium batteries too

It’s also ideal for GSX-R series.
I think they’ll be gone soon

Only selected buyers might be able to purchase them
The reality might be harsh (；∀；)

Rear generators are
on motorcycles
already a thing of the past

If they’re still loved today
it’s still safe
However

In reality that’s not the case＝they’re being phased out
the trend

Overhaul or new

Replacement parts are also tough
M-TECH, who can’t stop loving oil-cooled bikes

IC Regulator
Brush Holder

Applicable Models:
GSX-R750　F～M　WN～SPR　
GSX-R1100　G～N　W　GSF1200 and others

It’s helpful that they sell
the regulator and brush.

My thoughts on options

New Plan　1100/1200
31400-03F40＝31400-03F41 ConsolidatedBuy and sell used
Overhaul Plan (Labor costs separate)
GSX-R750/1100 and GSF1200
Purchase M-TECH kit and keep
IC Regulator　Brush Holder
Overhaul Plan (Labor costs separate)
Inazuma/Bandit/GS1200SS
Purchase Suzuki genuine and keep

So?
Which is better value, new or overhaul?
New and labor costs are only a few tens of thousands of yen more

Everything from the body is brand new♪
Should be good for 100,000 km
So you’re fine while you own it.

The gear outer diameter (tooth count) is
different so be careful

When you buy new
the damper base is not included
Pull it out with a puller and reuse
or you can get this new too.
